The petrophysical analysis of the early Eocene Sui Main Limestone (SML) has been conducted in Kharnhak-1 well for the prospect of the hydrocarbon exploration of the Khairpur-Jacobabad High, Middle Indus Basin, Pakistan. The petrophysical analysis of SML is carried out on the basis of well logs including gamma ray, spontaneous potential, resistivity, neutron, and density logs. These analyses lea...

based on the {s+, i-} pathway, the concentration of surfactant and surface charge density of silanolate groups control the phase transition from lamellar, to hexagonal through cubic form. the high surface charge density of silanolate groups was observed for the lamellar phase. with decrease of molar concentration of surfactant on the gel, the yield of reaction decreases and the stability of mes...

background: poisoning is considered an important public health issue. considering the high prevalence of poisonings and the diversity of their ensuing symptoms, this study aimed to investigate the epidemiology of the clinical symptoms of poisoning in children admitted to shahid madani and ta'min ejtema'i hospitals of khorramabad in 2011. methods: in this cross-sectional study, the dat...

Rates of hydrocarbon biodegradation were estimated by following oxygen uptake during mineral oil oxidation or oxidation of [1-14C]hexadecane to 14CO2, when these substrates were added to natural water samples from Wisconsin lakes. A lag phase preceded hydrocarbon oxidation, the length of which depended on population density or on factors influencing growth rate and on the presence of nonhydroca...

Oily sludge (OS) degrading potentials of single and consortium autochthonous bacterial population was carried out using standard analytical procedures. Three species; Pseudomonas aeruginosa, Bacillus cibi subtilis were associated with the OS. The isolates exhibited varying OS utilizing biosurfactant producing potentials. P. aeruginosa best utilizer while B. producer (emulsification index 15.6%)...

The industry demands high quality and standards-compliant beeswax, which is difficult to find in western countries. As a result, it necessary explore new geographical sources. This work focuses on the characterization of beeswax from Mozambique terms saturated hydrocarbon profile thermal properties comparing them with others diverse origins. hydrocarbons found (C21H44-C35H72) do not contain eno...

To extract chemical information reliably, we propose a new data processing method based both on the creation of vectors and vector base change. The originality this is combination different core XPS peaks, Auger and/or valence bands in single vector. We show that measurement sample upon its progressive change, such as accumulation adventitious carbon, allows us to create basis using linear alge...

Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon f...
